A classroom setup is not the perfect platform for Hands on Science and I am very happy that SciPie Club has taken this initiative of teaching science with a hands on approach.

Parent Comments

I am so happy that someone is doing all the science related experiments which are only available on websites and on Youtube. I really enjoyed the parents and kids science workshop organised by SciPie Club. Looking forward to regular courses for my kid. – Mohit Singha

Kids Comments

I love science but there was no way to practice the experiments. At SciPie Club I really enjoy the practical applications of concepts I learn in class. – Abhijeet Sharma (Class 6th Student).

Had a great session ! Looking forward for more fun with science.
